[meta] Ensure compatibility of Drupal 9 with PHP 8.0 (as it evolves)

What's the next step here? The PHP team is using the master branch for PHP 8 (7.4 is branched), so should we ask for a DrupalCI environment with master or is it too early to get anything useful out of it?

Schedule of PHP8 releases published https://wiki.php.net/todo/php80

• The PHP 7.4 issue is fixed, so this no longer needs to be postponed.
• Converting to a meta because there will probably be many specific changes needed.
• D8 will also need PHP 8 support, and we'll want to backport bugfix-eligible changes to the production branch, so setting to 8.8.x for now. (Most changes will probably only land in 8.9 once it becomes the bugfix branch, but the issue will be bulk-updated.)

I'm not sure a DrupalCI environment with PHP's master branch is going to work out well, but we should at least file an issue in the infra queue to add an alpha1 environment once that's available in mid-June.

I have deployed the php8.0.0alpha1 containers to drupalci.

There are two available:

one which causes drupalci to use --ignore-platform-reqs on composer installation so that we can actually start the tests, (example test run here: https://www.drupal.org/pift-ci-job/1745431)
and one which does not do that so we can see the composer errors and attempt to get them fixed upstream. (example test run here: https://www.drupal.org/pift-ci-job/1745432)

Filled followup #3156542: \ReflectionParameter::getClass() is deprecated in PHP 8.0

Cross-posting: https://github.com/symfony/symfony/issues/36872

Opened #3156558: Upgrade dependencies prior to 9.1.0 to try bumping our symfony dependency version to at least 4.4.10.

Filled the issue for doctrine/reflection https://github.com/doctrine/reflection/issues/46

#3156595: Make Drupal 9 installable on PHP8 has a patch that allows Drupal to install on PHP 8 - but also shows some of the fun we're going to have because PHP 8 has scalar typehints on internally supplied classes like \PDO.

#3127141: Use PHPUnit 9 for PHP 7.4+, while keeping support for PHPUnit 8.4 in PHP 7.3 is a prerequisite for this issue.

Based on work on #3156595: Make Drupal 9 installable on PHP8 I've updated the issue summary with all the vendor fixes we need to make Drupal 9 green on PHP 8. Initial analysis looks good in terms of no of this requiring a new major version. But things are likely to be very tricky for Drupal 8 due to the PHP 7.0 compatibility requirement. For example, it's likely that the only compatible phpdocumentor/reflection-docblock with PHP 8 will have a minimum PHP version of 7.2.

For example, it's likely that the only compatible phpdocumentor/reflection-docblock with PHP 8 will have a minimum PHP version of 7.2.

No version of PHP prior to 7.2 is supported anymore, so I don't see this as a problem. It is reasonable that people upgrading their Drupal will upgrade their PHP to go with it. This is a policy change, however.

Adding the scope of work so far for Drupal changes. It's not too bad at all as far as I can see and much of it can be done for Drupal 8 & 9 now.

Unfortunately we can't just drop support for PHP 7.0 and 7.1 in our LTS release -- we would have had to make that announcement more than a year ago. So we might have to do some gymnastics or bridge code for specific dependencies that don't support all the PHP versions we do. (a.k.a. the "Drupal PHPUnit Challenge").

Another options is set requirements to prevent install LTS on php8 as suggested in #3156651: Prevent Drupal 8.9 and 9.0 from being installed on PHP 8

Fwiw #3156651: Prevent Drupal 8.9 and 9.0 from being installed on PHP 8 is kinda pointless atm - here's a list of vendor deps once we're run composer update that still don't support PHP 8. We've got a long way to with all of this...

Fixed issues sorted in summary, last php 8 alpha 3 will be released in 3 days, next checkpoint is Aug 3

#3161223: Use PHP 7.0 "spaceship" operator for user sort functions where possible

Updated summary.

#3161223: Use PHP 7.0 "spaceship" operator for user sort functions where possible is not necessary for PHP 8 compatibility as far as I can see.

@alexpott Ahh sorry. I saw it added as a child issue and was trying to keep the summary up to date.

It's valid issue, just hard to catch when weights are the same

commited #3156879: \Drupal\Component\Utility\Bytes::toInt() - ensure $size is a number type

New release of Symfony 4.4.11 adds support for union types and few bugfixes https://github.com/symfony/symfony/blob/4.4/CHANGELOG-4.4.md

Also composer 1.10.10 got fixed support for php8 https://github.com/composer/composer/releases/tag/1.10.10

Probably #3157296-14: Upgrade dependencies prior to 9.1.0 needs split for this changes

Filed separate issue #3163133: Upgrade composer/composer and phpspec/prophecy dependencies to support PHP 8.0
Because phpspec/prophecy and its dependency phpdocumentor/reflection-docblock got new releases containing fixes mentioned in IS

#3157296: Upgrade dependencies prior to 9.1.0 was committed on Tuesday; does that cover PHP 8 compatibility for all our dependencies?

I ran a test to find out: https://www.drupal.org/pift-ci-job/1810516 shows that there's a significant number of deps still incompatible with PHP 8.

Have php 8 compatible versions:

composer/composer -> 2.0.0-alpha3
composer/semver -> 3.0.0
phar-io/manifest -> 2.0.1
phar-io/version -> 3.0.2

Might be worth it to audit our usages of substr to see if we're expecting 'false' in any situation:

Re #70 I did check of core
Both substr() and mb_substr() has not a lot of usage with negative 3rd argument, but all places expect it returns string

symfony-cmf/routing 2.3.3 released via https://github.com/symfony-cmf/Routing/pull/255#issuecomment-704173314

Opened #3176576: Update to Symfony CMF 2.3.3.

Just committed #3176504: Upgrade dependencies prior to 9.1.0 which updated symfony-cmf and others.

Another dependency doctrine/reflection#43 sounds like it needs replacement for PHP 8
So could be solved in #3156542: \ReflectionParameter::getClass() is deprecated in PHP 8.0

Adding #3177541: stream_open() needs to cope with a failure in \Drupal\Core\StreamWrapper\LocalStream::getLocalPath() better

Adding #3177545: \Drupal\field\Entity\FieldStorageConfig::getCardinality() needs to be more type safe

Adding #3177590: ViewsFormBase::getForm() re-uses $key and relies on odd PHP 7 behaviour

Updating todo -> done

Added the missing #3177557: \Drupal\error_test\Controller\ErrorTestController::generateWarnings() notice is not a notice in PHP 8

Adding #3178998: Update error types and messages for PHP 8

Updating IS.

I opened a new PR against doctrine/reflection for PHP 8 compatibility - and it's got a bit more of a positive feedback - see https://github.com/doctrine/reflection/pull/43 - upldating issue summary to point to the open PR.

Thanks to Alex https://github.com/doctrine/reflection/pull/49 is merged

Adding #3179284: Update dependencies for Drupal 9.1 and 9.2 to issue summary and updating title to reflect discussion with @catch and @xjm about likely compatibility with Drupal 8 and PHP 8

Updating issue summary with recent progress.

Updating current state.

While we usually are strict about not backporting things like dependency updates after beta1, in the case of these issues I think we should at least consider backports up to RC1 (because PHP 8 compatibility in 9.1 would be groovy). I'd suggest:

1. Commit any PHP 8 compatibility fixes to both 9.2.x and 9.1.x up until the release of 9.1.0-beta1. Indicate in the beta1 release notes which blockers are outstanding and that those blockers may result in additional dependency updates after beta1.
    

2. After 9.1.0-beta1, commit PHP 8 fixes to 9.2.x as they're available.
    

3. If all PHP 8 fixes land in 9.2.x prior to 9.1.0-rc1, backport them to 9.1.x at the same time once that's achieved. Release 9.1.0-beta2 with these fixes unless it's already the RC window.

Changing the version to 9.1.x because, as discussed in #3156651: Prevent Drupal 8.9 and 9.0 from being installed on PHP 8, the release and framework managers have agreed that these changes are too disruptive for 8.9.x to support PHP 8.

Discussed further with @catch. It's possible that some of the remaining blockers could be solved with patch releases of the affected dependencies. Patch-level updates are technically backportable during any release phase, including in patch releases (with a release note and a good reason), so those could be backported as they land. We'll evaluate each issue as it gets committed to 9.2.x.

Updating issue summary with current state and moving #3176655: Deprecate GoutteDriver use in core and use Behat\Mink\Driver\BrowserKitDriver directly instead to the Drupal list as this is the most likely place it is going to be solved.

Did some work on a pull request for typo3's stream wrapper... https://github.com/TYPO3/phar-stream-wrapper/pull/65

We've got a new issue due to a fix in PHP 8's MySQL layer - #2736777: MySQL on PHP 8 now errors when committing or rolling back when there is no active transaction

https://github.com/laminas/laminas-feed/pull/29/files merged compatibility but now it require phpunit9

@andypost the phpunit 9 requirement is a dev requirement. It matters not.

updated IS cos commited #3180092: Update fabpot/goutte to 3.3.1 for PHP 8 compatibility

Only one core issue left and few dev-dependencies

Filed 2 PRs to help finish https://github.com/laminas/laminas-diactoros/pull/46#issuecomment-720152303

https://github.com/TYPO3/phar-stream-wrapper/releases/tag/v3.1.6 is out with both PRs merged

Filed child issue #3181240: Upgrade typo3/phar-stream-wrapper 3.1.6

looks it should be backportable to 9.1 at least in next minor

Added two new Drupal issues that help with running tests on PHP 8.0 and updated summary.

Updating list of issues.

Drupal 9.1 and Drupal 9.2 are both PHP 8 compatible according to our tests and are composer installable.

Going to mark this as RTBC

We're still awaiting a release of behat/mink-selenium2-driver but we've got a work around in 9.1.x and 9.2.x and there is a follow-up already to remove the work around when we update.

I've credited all the commenters on this issue.

It will need to update docs at https://www.drupal.org/docs/system-requirements/php-requirements

It is released https://www.php.net/archive/2020.php

Great landing with main changes (multilingual)
https://www.php.net/releases/8.0/

Updated IS after PHP 8.0.0 release.

Originally didn't think there was any chance of getting it done for 9.1.x, then suddenly it seemed in grasp, then it didn't again, then we got there at the last minute.

I don't think there's anything else to do in this meta, and https://www.drupal.org/docs/system-requirements/php-requirements is updated, so marking fixed!

Congratulations 🎉 btw json extension should be bundled since 8.0 but there's still ability to build it shared so makes sense to keep it in requirements

Problem/Motivation

I am going through the process of upgrading from D7 to D9 and also upgrading PHP71 to PHP74 or PHP80. So I am running PHP_CodeSniffer-3.6.1 and PHPCompatibility-9.3.5 on the Drupal codebase to test for issues.
Steps to reproduce

Install D9 and PHP_CodeSniffer-3.6.1 and PHPCompatibility-9.3.5. Run the test.
Proposed resolution

Maybe someone should review the warnings and errors below to see if there are any real issues. I see that D9 claims to support PHP80 from D9.1.0. However, D9.2 is spitting out of lot of warnings and errors from PHP_CodeSniffer-3.6.1 and PHPCompatibility-9.3.5.

Errors and warnings list inline below and attached as csv.
